FRANK F. WEAR, OF SAN FRANCISCO, CALEFORNIA, ASSIGNOR, BY MESNE ASSIGN-MENTS, TO TOLEDO SCALE COMPANY, OF NEXVARK, NEl/V JERSEY, A CORPORATIONOF NEW JERSEY.

Application filed May 23, 1904.

To all whom it may concern:

Be it known that I, FRANK F. Val-in, a

citizen of the United States, residing at San Francisco, San Franciscocounty, California,

. have invented certain new and useful Imboth by hand and in anautomatic manner,

as hereinafter made apparent.

In the drawings, Figure 1 is a side elevation of a scale embodying myinvention with a portion broken away to expose the new parts; Fig. 2 anenlarged detail view of such new parts; Fig. 3 an end view of suchparts, and Fig. ,4 a detail view of the regular pendulum weight and thesupplemental or removable weight.

The particular form of pendulum scale is not material, inasmuch as myinvention may be applied to any of those in common and well known use,and hence no detailed description of the scale is necessary. It willsufiice to say that the scale beam or lever 1, on which is pivoted asuitable load platform 1, is operatively connected with the disk 2 fromwhich depends the pendulum rod 3 having thepermanent pendulum weight 4,and from which extends the usual pointer or hand 5 arranged to sweepover the price computing table or chart As shown in Fig. 1, the pendulumis provided with the extra or removable pendulum weight 7, so that thescale is now capable of weighing and computing according to itsincreased capacity, and the object of my invention is to provide meansfor the attachment and detachment of such removable weight without thenecessity of the actual handling of the weight by the op erator, withconsequent inconvenience and liability of slight misplacement of the reSpecification of Letters Patent.

movable weight, which might prevent accurate weighing and computing.

It will be understood that provision is made for the difierent readingsaccordingly as the removable weight is in use or not, and, as usual insuch cases, I provide on the chart and pointer black figures to be readwhen only the permanent pendulum weight is used, and red figures whenboth weights are used. Likewise the removable weight may be painted acontrasting color, such as red, to distinguish it from the other weightwhich may be painted black.

Extending transversely and journaled in the walls 8 of the scale casingis a rock shaft 9, from which depend two similar arms 10 having hubs 11secured to the shaft. This shaft projects through the front wall of thescale casing and is there provided with an operating handle 12 withineasy reach of the operator. These arms 10 are provided toward theirouter ends with cam surfaces 13 which are adapted to engage andcooperate with opposite and laterally projecting pins or studs 14: onthe removable weight or ball 7. Those arms serve as a cradle orsupporting frame for such removable weight in a manner and for a purposehereinafter made apparent.

Upon the rock shaft 9 and toward one end thereof is secured a disk 15having a cam surface terminating in a shoulder 16 adapted to be engagedand held, under certain conditions, by a lever or latch 17. This latchis pivoted at 18 to the rear wall of the scale casing, and its inner orupper end 19 is hook-shaped so as to engage the shoulder of the disk.This latch or le r has a. trip arm 20 extending laterally at r ghtangles in the path of swing of the permanent pendulum weight when swungslightly above or beyond its usual travel, particularly when swungquickly and somewhat violently, as when the normal capacity of the scalehas been exceeded. Now, assuming that the removable wei 'ht is in itsnormal position resting in the cradle, as seen in Fig. 2, and it isdesired to transfer or attach the same to the pendulum rod on top of thepermanent weight in order to increase the capacity of the scale. theoperator depresses the scale beam to such extent that the permanentnenduli. a rod ceive up in I may be m e action l o lo beamt 3 en" placedon tin the sca v \1 ses scale beam by pressir A down on the platter n orotherwiie, and then, by turning the lever 12 in the er direction, rocksthe shaft 9 so as to a. its cradle below the removable weic it and,

l by continued upward movement, to lrt't the same from the pendulum rod.Whei the cradle has been roc ed to the position shown in Fig. 2, thelatch 19 engages the dish and the cradle is thereby be d in elevatedposition. The ollice of the cam fa on the cradle arms is to ift theremovable weight bodily from the permanent weight in a direction loitudnn of tn. .lun so nent weight.

As hcreinbe'fore Sta tec contrasting colors such as black and rec nploycd for an with the wordsltead red figures, or may readily know by iresot. the chart This arm when in its i is weight is la iv i in the cradle,the position, 11 which cl to ex- Plead b the range apacity acaine may yand quickly increased by the opera 'or by f I) O L be incchanisuescribcd without the Ildfi ssi e remove l ty of his han- 1t, esideswhich the ana. cit T ie scale l.
